Abstract

Remote sensing of the atmosphere from space plays an increasingly important role in weather forecasting. Exploiting observations from the latest generation of weather satellites relies on an accurate knowledge of fundamental spectroscopy, including the water vapour continuum absorption. Field campaigns involving the Facility for Airborne Atmospheric Measurements (FAAM) research aircraft have collected a comprehensive data set, comprising remotely-sensed infrared radiance observations co-located with accurate measurements of the temperature and humidity structure of the atmosphere. These field measurements have been used to constrain the strength of the infrared water vapour continuum, in comparison with the latest laboratory and theoretical studies. The impact of these results on the remote sensing of water vapour from space is discussed.
